Did You try amx_bury command? It's not exactly the same, but the result for You should be the same - the burried bot will go nower, so You can shoot it with no answer from it.

Ya I am aware about amx_bury command but when I use this command the bot will go underground and his head will not be in the same position as it would be if I was to freeze it.
I want to practise spams and therefore I want to freeze them at a particular position.Can you do something so that in the next updated version people are able to freeze the bots.Thanks!
